To @ZZ whom z5 may concern,.-

Be it known that I, HENRY M. BURNETT, a citizen of the United States, residing at San Francisco, countyof San Francisco, and State of California, have invented certain new and Y useful Improvements in Laying-Out or Lining Devices; and I hereby declare the following to be a full, clear,and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to laying out or marking machine-work, technically called lining,77 and toa machine or implement whereby circular lines, spacing and subdivision of circularlines, determining and marking radial lines, also linesparallel to the axes of circular pieces, can be rapidly and accurately done.

My improvement consists of a supporting base or frame whereon is mounted a revoluble holding form or chuck provided with jaws or other suitable devices to hold and present the work to be lined, a circular spaced scale on the stationary base-plate, and a sectoren the movable plate or chuck provided with gages to determine various degrees vof arc through which the work is to be moved, adjustable marking implements mounted on axes fixed in respect to the revoluble plate or chuck, with various features of construction' and operation hereinafter more yfully explained in connection with the drawings.

The objects of my invention are to attain celerity and accuracy in laying out or lining machine-work and to avoid the use of instruments or templets commonly employed for this purpose.

Referring to the drawings, Figure yI is a plan view of one of my improved laying-out or lining machines with various marking implements mounted in position for use. Fig. Il is a side elevation of the same machine, some of the parts being shown in section. Fig. III is a detail section through the pivot on which the revoluble plate turns. Fig. IV is a side view of va cutting or scoring implement to it on the bar 11. Fig. V is a detail showing a section on the line 5 5 in Fig. II.

In the drawings, 1 is abase-plate on which the operating parts are mounted; 2, a revoluble chuck or holding form on which the work 3 Serial No. 665,537. (No model.)

torbe lined is mounted and held by the movable jaws 4. The rigid vertical standards 5, 6, and 7 are fastened in the base-plate 1 and are to receive and support the straight-edge from the center,and the straight-ed ge 8 swings on the standard 7 when detached from the standard 5, as hereinafter explained. All these bars having radial or swinging movement are held by the shell-supports 13, movable upward and downward on the standards 5, 6, and 7, clamped by means of the screwsv 14 and provided with collar-nuts 15, as shown in section in Fig. II. These shell-supports 13 form an especial feature of my invention, are interchangeable between the standards 5, G, and 7, and are applicable to implements of any kind that require pivoted support or revolve about a center. f

The straight-edge 8 swings on the standard 7, is notched at 16 to clear the middle standard 6, and is attached, when in a working position, to the standard 5 by a hinged clamp 17, pivoted 4at 18, that embraces the standard and hooks over the main bar S, as seen in Fig. V. The front orworking edge of this bar S coincides with axis of the chuck-plate 2 and has a scale of linear measures marked thereon,l as indicated in the drawings.

In using the trammel 9, -which is for scribing or cutting circular lines, the straight-edge 8 can be loosened from the standard 5 and swung out of the way. rIhis trammel,besides the scribing implement 9, is provided with an angular pointed tool 19, (shown in Fig. IV,) that will out an angular groove of any shape desired, that has the advantage of permanence, and assists in holding packing in lianged work laid out by the machine. The radius-as, for example, to the line m-is determined either from the scale of inches or other measure on the straight-edge 8 or by scale on the radius-bars ll, reading from the axis of rotation. The vertical scribing-bar 10 is employed in marking lines and positions parallel to the axis of rotation, suoli as dividing the periphery of flanges or other circular pieces into certain divisions or spaces, as hereinafter explained.

It will be understood that hand implements or others than are illustrated can be used to mark, line, scribe, or drill the work when adjusted, as hereinafter described.

Referring further to the revoluble form or chuck-plate 2, this revolves on the nipple 20, formed on the base-plate, and on the bushing 2l,which is clam pcd to the base-plate l Aby means of the nut 35 and is further secured by the screw-nut 22. This construction permits the removal of the central standard 6 when laying out work that is solid and has no central bore to accommodate the standard (3. To cause this chuck or plate 2, with the work held thereon, to revolve easily, I mount it on rollers 23, as shown in Fig. I. The work to be lined is adjusted and held by the jaws 4c, that are moved by screws 24 in the manner of a common chuck.

Referringto the adjustment for circular division, which is an important function of the machine or device, I drill around the outer edge of the base-plate l a row of accuratelyvspaced holes 25-for example, seventy-two in number-and on the side ot' the revoluble chuck-form 2 I attach a slotted sector 2G, provided with a spring stop-pin 27, that iits into the holes 25. rlhis pin 27 is iitted in a movable block 2S, that can be clamped to the sector 2G by means of the screw-bolt 29, that, like the stop-pin 27 ,passes through the slot 30.

The circular adjustment of the rcvoluble chuck 2 can be made in various ways. I have shown a very simple form consisting of a single row oi' holes 25, preferably seventy-two in number or some multiple of that number, and a spring stop-pin 27, having a point that iits into said holes 25, as shown in Fig. II. To support the said stop-pins or equivalent locking device, I attach to the side of the revolving chuck 2 a slotted sector 26, provided at one end with a micrometer-screw 34, fitting in a block 32, made integral with the sector 2G. The stop-pin 27 is mounted in a block 28, that can be clamped t-o the sector 26 bya screw 29, so as to hold the chuck 2 in a xed position when the work is being marked or lined. A movable stop 3G is also provided, so that in ease of loosening or moving the block 2S it can be returned again to the same position on the sector 2G.

In mounting the work, if there is a definite starting-point or divisions are to be made with respect to some line already made, the relation between such mark or point and the chuck 2 is adjusted by means ot' the microineter-screw. The work being fastened in the jaws 4, the point 53 of the micrometer-screw is brought into contact with the block 2S and the screw is turned to the right or left until the desired starting-point on the work is in alinementwith the straight-edge 8 or the vertical bar 10, after which the stop-pin 27 will make the required division. For finer divisions several circles of holes 25 can be drilled in the base-plate l in the usual manner of index or spacing plates for dividin g-machines. I do not confine myself to any particular inode or way or device for making this circular adjustment, as it can be performed in various ways-as, for example, by tangent or worin gearing, a pawl and ratchet, or other suitable known means that will produce the required spacing for lines or graduations.

I claim as new and desire to secure by Letters Patentl.
